SAMUEL MITCHELL, OF LIMA, NEW YORK.

VEHICLE-WHEEL HUB.

SPECIFICATION forming part of Letters Patent No. 232,837, dated October 5, 1880. Application filed January 5, 1880.

To all whom it may concern:

Be it known that I, SAMUEL MITCHELL, of Lima, in the county of Livingston and State of New York, have invented a certain new and useful Improvement in Hubs; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure 1. is a plan of the hub. Fig. 2 is a central longitudinal section. Fig. 3 isa crosssection. Fig. 4 is an elevation of one of the rings or bands which bind the hub.

My improvement relates to that class of hubs in which bands are used surrounding the hub for the purpose of strengthening the same, said bands being located some distance from the spokes, and not coming in contact therewith.

The invention consists of bands wedgeshaped in cross-section, and provided with eyes projecting inward to receive bolts or rivets which extend from one band to the other beneath the surface of the hub, as hereinafter more fully described.

In the drawings, A represents the hub, which is of usual form, and is provided with mortises a a, in which the spokes rest, with the ordinary wedge-shaped webs I) b between the mortises.

B B are the two rings or bands which oncircle the hub on opposite sides and at some distance from the spokes. These rings are of wedge shape in cross-section, the thin edges being placed inward, and the surfaces or seats of the hub on which they rest are correspondingly inclined, so that as the rings are pressed in toward each other they will bind closer and closer on the hub.

G C are rods or bolts which extend longitudinally from one ring to the other through the wood of the hub, resting in holes bored longitudinally through the hub, and passing through the webs b b between the spokesockets, as shown in Fig. 3.

If desired, a bolt may pass through each web and between each two of the spokes; but a smaller number is generally suli lcient, and but four of such bolts are shown in the draw- 1n gs.

The bolts or rivets are connected with the bands by passing through eyes or loops at d formed on the inner sides of the bands and at their rear edges. The bolts are tightened up at any time to draw up the bands by riveting up the ends, or by using threads and nuts, or by other suitable means.

By the use of the eyes or loops d d, as above described, the bands can be made very thin, so as to conform to the general surface of the hub without producing a high shoulder, and at the same time the bands are re-enforced at the points where the bolts connect and proper seats are provided for the bolts, which could not otherwise be done without increasing the thickness of the rings and making a corresponding high shoulder on the hub.

By the use of bolts or rivets, as described, the hub is greatly strengthened and braced both longitudinally and transversely, and the hub cannot easily break across the mortises.

Having thus described my invention, I do not claim, broadly, the use of bands con nected by rivets in a hub; but

What I claim as new, and desire to secure by Letters Patent, is-- The bands B B, made wedge-shaped in cross-section, and provided with the inwardly-projecting eyes 61 d for the reception of the bolts or rivets which connect thebands, as herein shown and described.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

SAMUEL MITCHELL.
